I tried to use my boss pedal plugged into the back of my Peavey today and it sounded like shit on, but to my surprise it sounded a lot better with the pedal off. By that I still mean plugged into the amp but just not on, after I unplugged the pedal to check sure enough it didn't sound as good.

So is that just normal? like some kind of boost or whatever? And can I harm my amp doing this.

Try plugging just a cable in from the fx send to the fx return, it doesn't harm your amp.

Yeah just a small cable did the same thing. I definitely think it makes a difference and personally I think it sounds better.

What kind of pedal were you using?

^^It doesn't matter what pedal is there -- something happens when you use the effects loop on that amp, even if it's just a 6" cable connecting the send and return jacks. In my opinion, it sounds overly harsh and fizzy, but that could be that I also use a boost up front. Without a boost pedal, the amp could use a little brightening. I run an EQ in the loop, however, and get a better sound regardless.

Peavey are not very good at designing amps, particularly loops.

But then again, to be fair, a lot of other companies aren't either.

Gotta look in the nooks and crannies to find a real beautifully designed amp with no stupid little problems like this. Usually gotta drop $$$ too, unfortunately.

I say this as someone who has owned a ValveKing, 5150, JSX, & 6505. I'm a little over it.

Cath, I've tried that with various new tubes, and it doesn't have any effect on this. It's like the effects loop has a built-in buffer -- and a bad one at that. There is a mod to make the effects loop true-bypass, but I haven't bothered with it, as I'm very happy with the sound I get with an EQ in the loop.

As Offworld pointed out, many amps in that price range have flaws. For $600, I'm pretty happy with what the amp is good at.

the buffer in the pedal is buffering the loop better than whatever peavey uses to drive the loop?

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.
